OILING MECHANISM FOR EXPLOSIVE-MOTORS.

Specification of Letters Patent.

out a pump or other driven parts, to utilize the pressure in the crankcase produced by escape of gas past thepistons to force the oil from the bottom-of the crank case into an elevated tank, then relieve the pressure and permit the oil to flow from the elevated tank to the splash pan. The other objects of my invention will more fully appear in the following specification and claims.

I attain these objects by the mechanism illustrated in the accompanying drawing which is a vertical section of the crank case of an explosive motor to which my invention has been applied. The crank case 1 is provided with a splash pan 2 of the usual type, provided with an overflow port 3. In open communication with the bottom of the crank case 1, at 4: is a pipe 5, the other end of which is in open communicationr with the elevated oil tank 6 at 7 near the top thereof. The tank 6 is provided with a breather 8 of the usual type. In open communication with the bottom of the tank6 is a pipe 9, which passes through the crank case 1 at 10 and discharges into the splash pan 2 at 11. A check valve 12 of the usual type is inserted in the pipe 9 to prevent the flow of oil from the splash pan 2 through the pipe 9 to the tank 6, but permits the oil in tank 6 to flow freely through the pipe 9 to the splash pan 2.

The construction is such that the gas which passes past the pistons into the crank case can only escape through the pipe 5 tank 6 and breather 8.

The operation of my mechanism is as follows l Oil is introduced into the tank 6 through the breather 8 and flows through pipe 9 past the check valve 12 into the tank 2, the surplus overflowing through the port 3 into the crank case 1, where it will rise to approxigines comprising in combination a crank mately the dotted line X-X, oil to the level of the overflow port 3 remaining in the splash pan 2. -lVhen' the engine is started, gas escapes past the pistons until the pressure is suflicient to force the oil in the bottom of the crank case 1 through the pipe 5 into the oil tank 6, when the pressure is reduced to normal or atmospheric pressure by the escape of gas through the pipe 5 tank 6 and breather 8. Then the oil continues to flow slowly from the tank 6 through the pipe 9 back to the pan 2, whence it over: flows through the port 3 or is splashed from the pan 2 and collected in the bottom of the crank case until it covers the discharge outlet at 4:, which seals the outlet of the crank case and causes the pressure to rise until it is suflicient to force the oil collected in the bottom of the crank case through the pipe into the oil tank 6, when as before described the pressure in the crank case is reduced to atmospheric pressure.

The check valve 12 prevents the escape of oil or gas through the pipe 9. The pipe 9 is of such capacity that the oil will flow in the desired quantity from the tank 6-to the splash pan 2. The flow may be regulated by the cook 13 and the mechanism should be so constructed and regulated that all the oil will not have been discharged from the tank 6 before oil will again be forced from the crank case to the tank 6. It is apparent that oil will flow from the tank 6 to the splash pan until the pressure is almost suflicient to force the oil from the crank case to the tank 6. The preferred mechanism shown and described may be modified in many respects without departing from the spirit of my invention.

I claim:

1. Oiling mechanism for explosive encase, a. splash pan mounted therein, an oil .tank, elevated about the splash pan, means for utilizing the pressure in the crank case to drive the oil collected-in the bottom of the crank case into the elevated oil tank, means for relieving the pressure in the crank case when the oil has been driven therefrom and means for permitting the oil in the oil tank to flow by gravity into the splash pan.

2. Oiling mechanism for explosive engines comprising in combination a crank case, a splash pan mounted therein, an oil tank elevated above the splash pan, means 7 for utilizing the pressure in the crank case to drive the oil collected in the bottom of the crank case into the elevated oil tank, means for relieving the pressure in the crank case when the oil has been driven therefrom, means for permitting the oil in the oil tank to flow by gravity into the splash pan, and a check valve adapted to prevent the flow of gas or oil from the splash pan to the elevated oil tank.

3. Oiling mechanism for explosive engines comprising in combination a crank case, a splash pan mounted therein, an elevated oil tank with a pipe in open communication with the bottom of the crank case and with the upper portion of the elevated oil tank, a breather in the oil tank, a pipe provided with a check valve leading from the bot-tom of the elevated oil tank to the splash pan, said check valve being constructed to prevent the flow of gas or oil from the splash pan to the oil tank.

Signed at New York city, in the county of New York, and State of New York, this 9th day of May, 1918.
